Staphisagria, Stavesacre. In large doses is an emetic, cathartic, and narcotic, rather unsafe in use. In small doses (f.e. or ec. tr., 1-5 to I I.) it is a stimulant tonic to the nervous system. of value in melancholic and hysterical conditions, but its chief value is as a soothing agent upon the genito-urinary organs. It has considerable reputation in irritation of the prostate, testicles, and vesicule seminales, arresting mucopurulent discharges, such as gleet. Nocturnal emissions in nervous and anemic men and incomplete urethral evacuations are relieved by it. The homeopaths employ it in recurrent styes, salivation, and crural neuralgia, as well as in "sexual sins."
The ec. tr. contains the fixed oil of the seed, and makes a milky admixture with water. Most tinctures are made of seed from which this oil has been expressed. The contention has been made, but not well sustained, that the oil possesses therapeutic value. Equal parts of the fluidextract and cologne water are used to destroy pediculus pubis and p. capitis.
It must not be forgotten that staphisagria is very poisonous, and its preparations must be used with care and discrimination. In my own experience, fairly good results have been obtained from small doses of the drug.
